      Researchers used satellite imagery and modeling from previous fires to determine that between 7,500 and 10,000 of the towering species perished in the fire. That equates to 10% to 14% of the world’s mature giant sequoia population, the newspaper said.

      “I cannot overemphasize how mind-blowing this is for all of us. These trees have lived for thousands of years. They’ve survived dozens of wildfires already,” said Christy Brigham, chief of resources management and science at Sequoia and Kings Canyon National Parks.

      The consequences of losing large numbers of giant sequoias could be felt for decades, forest managers said. Redwood and sequoia forests are among the world’s most efficient at removing and storing carbon dioxide in the atmosphere. The groves also provide critical habitat for native wildlife and help protect the watershed that supplies farms and communities on the San Joaquin Valley floor.

      Brigham, the study’s lead author, cautioned that the numbers are preliminary and the research paper has yet to be peer reviewed. Beginning next week, teams of scientists will hike to the groves that experienced the most fire damage for the first time since the ashes settled. The newspaper said the extent of the damage to one of the world’s most treasured trees is noteworthy because the sequoias themselves are incredibly well adapted to fire. The old-growth trees — some of which are more than 2,000 years old and 250 feet (76 meters) tall — require fire to burst their pine cones and reproduce.

      Scientists have known last year’s Castle Fire was probably the most destructive for California’s famously fire-resilient sequoias in at least 700 years, but a draft National Park Service report obtained by the Visalia Times-Delta puts a quantitative measurement on that fire’s climate-fueled toll.

      Between 7,500 and 10,000 monarch sequoias — about 10% to 14% of the world’s mature sequoia population — perished in the fire. “I cannot overemphasize how mind-blowing this is for all of us. These trees have lived for thousands of years. They’ve survived dozens of wildfires already,” Christy Brigham, chief of Resources Management and Science at Sequoia and Kings Canyon national parks, told the Times-Delta.

      Redwood forests are some of the world’s most efficient when it comes to removing carbon from the atmosphere, and also provide critical wildlife habitat and watershed protection for farmers and communities in the San Joaquin Valley. The loss numbers, derived from satellite data, will be confirmed visually when scientists are able to hike the high-elevation groves still covered in snow.

      “Not much in my life in the natural world has made me cry, but this did,” Nate Stephenson, a research ecologist for the U.S. Geological Survey who works in the park and has been studying sequoias for years, told the San Francisco Chronicle. “It hit me like a ton of bricks.”
